For information about the command output, see Listing iSCSI Targets on page 6.
iSCSI initiators can now access the target iqn.2014-04.com.vstorage:test1 via the portal 192.168.10.100.
2.2.1 Performance Tips
• Spread iSCSI targets evenly across nodes in the cluster. For example, ten nodes with one iSCSI target
per each will perform better than a single node with ten iSCSI targets on it.
• Fewer LUNs per more iSCSI targets will perform better than more LUNs per fewer iSCSI targets.
2.3 Listing iSCSI Targets
Using the vstorage-iscsi list command, you can list all iSCSI targets registered on a node or display
detailed information about a specific iSCSI target on a node.
To list all iSCSI targets registered on a node, run the command as follows:
# vstorage-iscsi list

To display detailed information about an iSCSI target registered on a node, run the vstorage-iscsi list
command with the target’s name as the option. For example:
# vstorage-iscsi list -t iqn.2014-04.com.vstorage:test1
Target iqn.2014-04.com.vstorage:test1:
